Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100130, here are decompositions:
- 61 + 100069 = 100130
- 73 + 100057 = 100130
- 127 + 100003 = 100130
- 139 + 99991 = 100130
- 223 + 99907 = 100130
- 229 + 99901 = 100130
- 271 + 99859 = 100130
- 307 + 99823 = 100130
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,130 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100130 first appears in π at position 127,821 of the decimal expansion (the 127,821ordinal-suffix:st digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
